TELEPHONE-DIRECTORY DEVICE.

Specification of Letters Patent.

Patented Mar. 2, 1920;

Application filed March 6, 1919. Serial No. 280,975.

To all whom t may concern:

Be it known that I, FRANK R. CHESTER, a citizen of the United States,residing at New York, in the State of New York, have invented certainnew and useful Improvements in Telephone-Directory Devices, of which thefollowing-is a specification.

This invention relates to new and useful `improvements in telephonedirectory deprovided with Vradial spaces for writing therein the namesof parties frequently called' or whose names and numbers are. de siredfor a particular urpose. A correlated disk cover by the rst disk isexposed Sufficient of the second disk is exposed to contain. a telephonenumber. The name disk is fixed' while the number disk is rotatable. Anindicator carried by the number disk overhangs the name spaces Vofthe'name disk and by rotating the number disk so that the indicator isbrought to a name the number of this party is displayed through the slotor if the number has not been written on its disk it may be written andwill be displayed at future operations.

It will be at once apparent that by the use of two disks a greaternumber of names may be written o-n the name disk as no space isnecessary for the numbers whlch are written separately .on the numberdisk. The diameter of the device may be kept within reason by the use oftwo disks and some: spare is left on the naine disk for other.purposes.-

The invention will be more readily understood from a reading of thefollowing speciication and by `reference to the accompanying drawings,in which an example of the invention is shown and wherein:

Figure 1 is a front` elevation of the device Fig. 2 is a rear elevation,and

Fig. 3 is a diametrlcal sectional view or the device showing it fastenedon a trans-r mitter by the mouth-piece.

1n the drawings the numeral 10 designates anannularmetal frame having anopen face and quadrilateral ribsll bisected by an integral ring 12 andradiating from a central rlng 13. This provides four segmental openings14 between the `ring 12 and the margin of the frame and a similar numberof openings 15 ybetween the rings. The ring 13 has a collar 16 withinthe frame. A name disk 17 of cardboard or other suitable material isfitted snugly into the frame so as `to surround the collar and fit theinner face of the annular flange 18 of the frame, which face may besuitably roughened for this purpose. The face of the disk is thusdisplayed at the openings 14 and l5. Within the openings 14 the disk 17is provided with radial Spaces or panels 17; while within the openings15 advertising or other matter may be p rmted.

A circular metal back plate 19 is mounted to rotate on the collar 16within the frame and is provided with four equally spaced lugs 20 `whichoverhang the flange 18 and bent upon themselves with their ends' 21bearing on the margin of the face of frame and serving to hold theframe.

and the back plate together. One of the lugs carries an index 22 on itsend 21 adapted to register with the spaces 17. The collar 16 may besecured to a transmitter A by a mouth-piece B, thus holding the frameand name disk 17 stationary. Each lug 20v serves as a finger rest forthe operator who uses the most convenient one and pulls down thereon torotate the back plate 19.

A number disk 23 of substantially the same diameter as the disk 17 is,fastened to the inner `face of the plate by bending opposed ears 24 overthe same. This disk 23 is rotated with the plate. The right hand rib 11has a slot 25 in its portion separating the adjacent openings 14. Thedisk 17 alsohas a slot 26 registering with the slot 25. The disk 23 isthus visible through the slots and is used for telephone numbers.P

1n arranged or preparing the disks the name of a. party as J. Doe iswritten im one of the spaces 17 and the plate 19 rotated so as to bringthe index 22 to register with this space as is shown in Fig.,1. Thenumber of this party which may be M-348 is written on the number disk 23through the slots. Other names and num bers are written in the samemanner. it is obvious that when a number is wanted it is Las;

merely necessary to rotate the plate until the index registers With thespace bearing the name of the party, whereby the disk 23 is rotated tobrlng the number into view through the slots. Names and numbers may beadded as desired. By bending the lugs 20 and ears 24: the parts may bedisassembled and new names and number disks inserted. The three ribs 11other than -that having the slot 25 may contain the emergency calls,such as the fire department, ambulance and police, or some other specialdesignation, the number being printed on the disk 23 so as to appearthrough the slots.

What I claim, is:

In a telephone directory device; an outer relatively stationary frameembodying an outer ring carrying a laterally extending flange, an innerhub to be clamped to the transmitter ofthe telephone, and radial ribsconnecting thel hub and outer ring, said radial ribslforming segmentalname openings, and one radial rib being provided with a number opening;a name disk adapted to be held stationary Within the outer frame byengaging Within the annular flange thereof, said name disk being adapt'-ed to be removed when desired and having portions for receiving nameswhich are visible through the name openings, said name disk beingprovided with a number opening in registration with the rst named num--ber opening; a back plate having an openlng to pivotally receive thehub of the outerl frame so that such back plate may be turned withrelation thereto, the back plate being spaced from the name disk, saidback plate being provided at its periphery with radial lugs bent to formsockets which slidably embrace the flange of the outer frame, one

socket havlng a polnter to coactwvith the` name disk; and a number diskarranged within thelange of the outer frame and sei i cured to the backplate for .rotation therewith, said number disk having numbers to bebrought to a position to' be viewed through said number openings.

In testimony whereof I aiix mysignature.

FRANK R. CHESTER.
